Can I grow my seedlings on the windowsill? Will I need grow lights?
Generally speaking, the light of a windowsill is not sufficient, nor does it come from overhead (to insure stocky plants instead of stringy ones that stretch and lean). And then there is the issue of drafts in the late-winter and early spring weeks when some seeds are started. So no, don’t use the windowsill, but instead create a seed-starting rig with lights.
